Carbon has by definition 6 protons. However, its many isotopes can have anywhere from 2 neutrons to 16 neutrons, with 6 neutrons being the most common (~95% of all carbon). Carbon has by definition <b>6 protons</b>.
How Many Carbon Atoms Are in a Cell? A cell with a volume of 1 Âµm 3 and a density of about 1 g/ml has a total mass of 10 â12 grams. From the formula C 4 H 7 O 2 N 1 and the weights of the elements, we derive a carbon con-tent of about 12 Ã 4/(12 Ã 4 + 7 + 2 Ã 16 + 14) = 48/101 or about one half of the dry mass.
